Selective mutism is an anxiety disorder in which a child — or less commonly an adolescent or adult — who is capable of normal speech in familiar settings consistently fails to speak in specific social situations where speech is expected, most typically at school or with people outside the immediate family.
Selective mutism is not a choice. The child is not refusing to speak out of defiance or stubbornness. They are unable to speak in the triggering situation — experiencing an anxiety response that effectively inhibits speech despite the child's wish, and often their evident distress at not being able to communicate.
Selective mutism is classified in DSM-5 as an anxiety disorder — reflecting its aetiology in anxiety rather than in language or developmental disorders. The child speaks freely at home with immediate family but becomes silent — or severely restricted in speech — at school, in social settings, or with unfamiliar people.
Selective mutism is more than shyness. It involves a specific, functionally impairing pattern of speech inhibition that interferes with educational participation and social development — and if untreated can affect a child's trajectory significantly into adolescence and adulthood.
Onset is typically before age five, most commonly identified when the child begins school and the contrast between home speech and school silence becomes apparent to teachers and parents.
Selective mutism is best understood as a manifestation of severe social anxiety in a child who has not yet developed the coping resources to manage it in social-communicative situations. Many children with selective mutism also display social withdrawal, heightened vigilance, clinging behaviour in unfamiliar situations, and difficulties with transitions.
The role of temperament is important. Children with selective mutism typically have an inhibited temperament — behavioural inhibition, wariness of novelty, and a strong physiological arousal response to unfamiliar social situations. This is a biological predisposition, not the child's or the family's fault.
Bilingual and multilingual children are at elevated risk, as are children who have recently immigrated or changed language environments. In the Israeli context, this is particularly relevant for families who have immigrated with Russian or English-speaking children — who face the double challenge of learning Hebrew alongside managing anxiety in a new social environment.
Early identification produces the best outcomes. Assessment should not be delayed — the longer the pattern is established, the more entrenched it becomes.
Assessment includes clinical interview with parents exploring developmental history, onset and pattern of mutism, family history of anxiety, and the child's behaviour across different settings; direct clinical observation of the child; consultation with the school; assessment of language development; and screening for broader anxiety and neurodevelopmental presentations.
At IsraClinic, selective mutism assessment is provided by a multidisciplinary team including psychiatric assessment and specialist input from Lihi Givol — parent guidance specialist and expressive arts therapist with extensive experience working with children, adolescents, and families.
Importantly: the initial assessment of a child with selective mutism does not require the child to speak. Clinicians experienced in this area conduct meaningful assessment through observation, play, and non-verbal interaction.
Behavioural approaches — stimulus fading, shaping, and positive reinforcement — are the gold-standard psychological intervention. These involve carefully structured activities that progressively expand the situations in which the child can communicate, beginning from a position of safety and moving incrementally toward target situations. This is not about forcing the child to speak — it is about creating conditions in which speech becomes possible.
Play therapy and expressive arts provide non-verbal pathways to the therapeutic relationship and support the child's emotional processing alongside the behavioural work.
Parent guidance is a critical component. Parents learn how to respond to the mutism in ways that reduce rather than inadvertently maintain the anxiety — avoiding accommodation behaviours that short-term reduce distress but long-term reinforce avoidance.
School collaboration is essential. Effective treatment requires coordinated work between the clinical team, parents, and the school — ensuring the behavioural programme is consistently implemented across settings.
Pharmacotherapy — typically SSRIs — may be indicated in more severe or persistent presentations. Medication is prescribed individually. Digital prescriptions are issued through the Yarpa system.
All treatment is delivered within the framework of the Psychoergonomic Method.
If a child consistently fails to speak in school or other social settings despite speaking normally at home, or if social withdrawal is significantly affecting educational participation and peer relationships — specialist assessment is appropriate. Early identification is associated with significantly better outcomes.
IsraClinic accepts patients for in-person consultation in Tel Aviv and online, in English, Russian and Hebrew. No referral is required.
